Abstract

Membranes suitable for microfiltration, ultrafiltration (UF) and nanofiltration (NF) filters are provided. Such membranes may include a nanofibrous scaffold, optionally in combination with a non-woven substrate and/or a coating of a polymer and a functionalized nanofiller. Suitable membranes may also include a coating of a polymer and a functionalized nanofiller on a substrate, which can include a non-woven membrane, a nanofibrous scaffold, or both.
